Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597484, here are decompositions:

13 + 31597471 = 31597484
31 + 31597453 = 31597484
67 + 31597417 = 31597484
73 + 31597411 = 31597484
223 + 31597261 = 31597484
241 + 31597243 = 31597484
271 + 31597213 = 31597484
307 + 31597177 = 31597484

Showing the first eight; more decompositions exist.
